I've stayed in HOME INNs lots of times. Found them cheap and clean. No bar fridges. Handy to transport.
They are used by traveling govt workers who can apparently get discounts. Like, teachers. You can be a member too, and get other discounts.
It's hard for me to tell actually, what kind of discounts, because Mrs N gets discounts all the time.
For example getting Lotus and I into a closed museum in Kunming for free because the owner assumed she was our guide. She has got kickbacks for taking 'tourists' (ie, me) into shops.
Anyway, I found Home Inns convenient, cheaper than others in the same range, and they all have free water. We have found them in every city we have been to in China (except Hong Kong).
